Abstract
The utility model discloses a connecting structure of a metal embossed layer heat shield, which comprises a heat shield, wherein a heat insulating layer is filled in the heat shield and then is fixed on a pipeline of an exhaust system; the heat shield is characterized in that a U-shaped connecting structure is adopted at the position of a corrugated pipe of an exhaust system pipeline between the heat shields, and the heat shields are mutually lapped; therefore, the connection requirement of the heat shield can be effectively met, the free movement amount of the corrugated pipe is met, the product quality is improved, the advantages of good connectivity, reliability in use and the like are achieved, the connection failure of the heat shield caused by the movement amount of the corrugated pipe is effectively reduced, and the heat shield has obvious technical advantages, application value and economic benefit.
Description
Technical Field
The utility model relates to the technical field of heat-insulating protective covers of exhaust systems, in particular to a connecting structure of a metal embossed layer heat-insulating cover.
Background
The heat shield is mainly a protective product for vehicles and has the advantages of heat insulation, noise reduction, light weight, rust prevention and attractiveness. With the demand for engine emissions, the increasing necessity of installing such heat shields is increasingly recognized, along with the associated performance requirements for the heat shield.
At present, the conventional connection modes of the metal embossed heat shield generally include two modes, one mode is to wrap the heat shield together with an exhaust system pipeline and a corrugated pipe (as shown in fig. 2), and the deformation or the fracture of the heat shield can be caused due to the deformation of the corrugated pipe, so that the heat shield falls off; the other is to wrap the heat shield only on the exhaust system pipeline (as shown in fig. 3), and this way can cause the temperature of the nearby pipe to be higher and affect the performance of the whole vehicle because the corrugated pipe is not wrapped by the heat shield.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a connecting structure of a metal embossed layer heat shield, aiming at the defects of the prior art.
The technical scheme provided by the utility model is as follows: a connecting structure of a metal embossed layer heat shield comprises the heat shield, wherein a heat insulating layer is filled in the heat shield and then is fixed on a pipeline of an exhaust system; the heat shield is characterized in that U-shaped connecting structures are adopted at the position of a pipeline corrugated pipe of an exhaust system among the heat shields and are mutually overlapped.
Preferably, a gap is reserved between the overlapped parts of the U-shaped connection between the heat shields.
The utility model has the beneficial effects that: 1. the heat shields are mutually overlapped through the U-shaped structures, so that the moving quantity of the corrugated pipe of the exhaust system pipeline can be effectively met, the design requirement and the quality of a product are met, and the protection function is realized; 2. the U-shaped mutual overlapping is adopted, so that the strength is high, the reliability is high, the cost is saved, and the efficiency is high; 3. the corrugated pipe heat shield has the advantages of reasonable design, good connectivity, reliable use and the like, effectively reduces the deformation and the falling off of the heat shield caused by the movement of the corrugated pipe, and has obvious technical advantages, application value and economic benefit.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an installation of a prior art heat shield;
FIG. 3 is another prior art heat shield installation.
In the figure: 1 first heat shield, 2 second heat shield, 3 exhaust system piping, 4 bellows.
Detailed Description
The utility model is described below with reference to the accompanying drawings.
As shown in fig. 1, a connection structure of a metal embossed layer heat shield comprises a heat shield, wherein the heat shield is formed by filling a heat insulating layer after a plurality of metal embossed plates are molded, and the heat shield is fixed on an exhaust system pipeline 3 by welding, so that functions and effects of heat preservation, heat insulation, protection, attractiveness and the like are realized; the adjacent heat shields, namely the first heat shield 1 and the second heat shield 2 adopt U-shaped connecting structures at the position of a corrugated pipe 4 of an exhaust system pipeline, are mutually overlapped, and a gap 5 is reserved between the overlapped parts of the two; therefore, the moving amount of the corrugated pipe of the exhaust system can be effectively met, the design requirements and the quality of products are met, and the protection function is realized.
It should be understood that technical features not described in detail in the specification belong to the prior art. Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, which are only illustrative and not restrictive, and those skilled in the art can make various modifications without departing from the spirit and scope of the utility model as defined by the appended claims.
